Social Insurance Collection Mode、Enterprise Performance And Optimum Range Of Contribution Rate

On July 20,2018,the State Council clearly stipulated that all social insurance will be collected uniformly by tax authorities since 2019.The"double collection"mode of social insurance contribution implemented over the years in China will be transferred to the mode of unified collection and management by tax authornties.The adjustment of social insurance collection mode is the beginning of strengthening the management of social insurance collection,improving the efficiency of social insurance collection,and realizing the unified management of social insurance and taxation.As the main contributor of social insurance,the adjustment of the collection mode will obviously increase the burden of social insurance contribution,threaten the survival of enterprises and reduce the vitality of the market and economy.How can the collection and management of social insurance contributions achieve the reform effect of"generally not increasing the burden of enterprises"?How can it improve the collection efficiency and promote the fairness of the burden among enterprises?The purpose of this paper is to accurately and systematically evaluate the impact of the adjustment of social insurance collection mode on cost and operating performance of enterprises,and then provides an empirical reference for improving the social insurance collection system and reducing the burden of enterprises.From the view of the actual social insurance contribution rate of enterprises,I estimate and analyze the impact of the adjustment of social insurance collection mode on cost and operating profit of enterprises through making research on the financial data in 2016 of the 2913 listed companies which is in Shanghai and Shenzhen stock market.The study finds that the reform will obviously increase the burden of social insurance contribution and have a great impact on the cost and net profit of enterprises.There will be a considerable increase in cost and a decrease in profit in the coastal developed provinces,private enterprises,modern service industry and manufacturing industry.At the same time,in order to achieve the reform effect of"generally not increasing the burden of enterprises”,I use Cobb-Douglas production function to measure the maximum payment ability of different types of enterprises,and further choose the statutory contribution rate and the degree of administration as two main sensitive factors to carry out sensitivity analysis.The results show that the optimum range of statutory contribution rate of basic social insurance for Chinese enterprises is[17%,23%].The innovation of this paper lies in two aspects.On the one hand,unlike previous research which makes qualitative study on social insurance system,I make a quantitative analysis of the impact of the adjustment of the social insurance collection mode on the cost and profit of enterprises from the perspective of the actual social insurance contribution rate.On the other hand,this paper synthetically estimates the impact of the adjustment of social insurance collection mode on enterprises by constructing indicators such as overpaid amount,cost pressure index and profit shock,and measure the optimum range of statutory contribution rate of basic social insurance for Chinese enterprises,which provides a relatively reliable reference for the scheme of reducing the statutory social insurance contribution rate.
